(1)
Represents the yield on U.S. Treasury securities with a term consistent with the expected term of the stock options.
(2)
Primarily based on the historical volatility of the Company's common stock over a period consistent with the expected term of the stock options.
(3)
Beginning in 2016, the Company calculated the expected term assumption using the midpoint scenario, which combines historical exercise data with hypothetical exercise data for outstanding options. The Company believes this data currently represents the best estimate of the expected term of new employee options. Prior to 2016, the Company utilized the simplified method to calculate the expected term.
(4)
The Company does not currently plan on paying regular dividends.

The number of performance-based RSUs that are ultimately earned may vary from 0% to 200% of target depending on achievement relative to the predefined financial performance targets.
